[0037] Combination Figure 1-2 This application describes a wafer loading device provided in an embodiment, the device comprising:
[0038] The loading platform 1 includes a placement plane 11 for placing wafers of different sizes.
[0039] The wafer edge-finding mechanism 2 includes a wafer image acquisition device 21, a first driving device 22, and a first transmission device 23. The wafer image acquisition device 21 is disposed above the placement plane 11. The first driving device 22 is drivenly connected to the first transmission device 23, and the transmission end of the first transmission device 23 is fixedly connected to the wafer image acquisition device 21 so that the wafer image acquisition device 21 moves under the drive of the first driving device 22 to acquire wafer images.
[0040] In this embodiment, the wafer image acquisition device 21 is used to acquire at least a portion of the surface image of the wafer; the first driving device 22 is used to drive the first transmission device 23 to operate, and the first transmission device 23 drives the wafer image acquisition device 21 to move under the drive of the first driving device 22; preferably, the wafer image acquisition device 21 moves toward the edge of the wafer; the direction toward the edge of the wafer includes the direction away from the edge of the wafer and the direction closer to the edge of the wafer; preferably, the wafer image acquisition device 21 can move in a straight line toward the edge of the wafer; it should be noted that in actual applications, the wafer has a missing edge, and the wafer edge finding mechanism 2 can find the missing edge position of the wafer.

Different acquisition ranges can adapt to wafers of different sizes. For example, a first-size wafer corresponds to a first acquisition range, and a second-size wafer corresponds to a second acquisition range. The movement of the wafer image acquisition device 21 can switch between the first acquisition range and the second acquisition range.

[0053] In a specific embodiment of this application, the controller 3 is used to receive the image acquisition signal from the wafer image acquisition device 21, and to control the operation of the first drive device 22 based on the wafer size information.
[0054] In this embodiment of the application, by setting the controller 3, automated control is achieved, thereby improving the intelligence of wafer loading; and by setting the accommodating space 12 below the placement platform and placing the controller 3 in the accommodating space 12, most of the wiring connected to the controller 3 can be placed in the accommodating space 12, thereby improving the regularity of the loading processing equipment and reducing the size of the wafer loading equipment.

[0069] In a specific embodiment of this application, the second fixing plate 442 is at a 90° angle to the second fixing plate 442, forming an L-shaped plate.
[0070] In one specific embodiment of this application, the first fixing plate 441 can be connected to the second fixing plate 442 via a hinge, thereby facilitating the adjustment of the position of the information image acquisition device 41.

[0090] In this embodiment of the application, by setting up an ion fan 5, and the air blown by the ion fan 5 can reach the placement plane 11, the static electricity in the wafer loading process is reduced, thereby improving the reliability of the wafer loading process.

[0099] The working principle of the wafer loading equipment in the embodiments of this application is described below:
[0100] Before wafer processing, controller 3 receives wafer size information and sends electrical signals to the first drive device 22 and the second drive device 42 to control the wafer image acquisition device 21 and the information image acquisition device 41 to reach the positions corresponding to the size information. For example, if the wafer size is 6 inches, controller 3 sends control electrical signals to the first drive device 22 and the second drive device 42 to make the wafer image acquisition device 21 move along the wafer edge to position A corresponding to 6 inches, and the information image acquisition device 41 move along the wafer edge to position B corresponding to 6 inches. If the wafer size is 8 inches, controller 3 sends control signals to the second drive device 42 to make the wafer image acquisition device 21 move along the wafer edge to position C corresponding to 8 inches, and the information image acquisition device 41 move along the wafer edge to position D corresponding to 8 inches.
[0101] When the wafer image acquisition device 21 and the information image acquisition device 41 reach the position corresponding to the size information, the wafer begins to be transferred to the top of the loading platform 1. When the wafer is transferred to the top of the loading platform 1, the telescopic structure in the lifting device 14 supports the wafer and gradually lowers it to the rotating surface corresponding to the rotating device 13 so that the wafer is placed on the placement plane 11.
[0102] At this time, the wafer image acquisition device 21 and the information image acquisition device 41 start working. Specifically, the wafer image acquisition device 21 acquires at least a portion of the image information of the wafer and sends the electrical signals corresponding to the at least a portion of the image information to the controller 3. The controller 3 determines the orientation of the wafer on the placement plane 11 based on the at least a portion of the image information. Then, based on the orientation of the wafer, the rotating device 13 is controlled to rotate the wafer to adjust the orientation of the wafer. The information image acquisition device 41 acquires the identity information of the wafer and sends the identity information of the wafer to the controller 3. The controller 3 stores the identity information of the wafer for subsequent management and tracking of the wafer. Preferably, the controller 3 can send the identity information of the wafer to the cloud server and store it on the cloud server.
[0103] The wafer loading equipment in this embodiment of the application has the following beneficial effects:
[0104] By setting a first driving device 22 and a first transmission device 23 in the wafer edge finding mechanism 2, the first driving device 22 drives the first transmission device 23 to move, and the transmission end of the first transmission device 23 drives the wafer image acquisition device 21 to move, thereby changing the acquisition range of the wafer image. Different acquisition ranges can be adapted to wafers of different sizes. For example, a wafer of the first size corresponds to the first acquisition range, and a wafer of the second size corresponds to the second acquisition range. The movement of the wafer image acquisition device 21 can switch between the first acquisition range and the second acquisition range. This adapts to the edge finding processing of wafers of different sizes, improves the versatility of the wafer loading equipment, and reduces the cost of aging tests.
[0105] This application also provides a wafer aging test device, which includes the wafer loading device in this application embodiment. The beneficial effects of the wafer aging test device are the same as those of the wafer loading device described above, and will not be repeated here.
